The following is a report comparing COPD patients EMR recorded exacerbations from March - September 2018, March - September 2019 and March - September 2020. The population was restricted to 15,029 patients from 263 practices that had an audit date after Sept. 2020.
2 Population Selection
3 Overall Exacerbation Rates
Exacerbation rates were comapred using patient’s EMR looking atMarch - September 2018, March - September 2019 and March - September 2020. These are split into 3 categories, each containing patients that have had at least 1 of the following:
